Colloidal and micellar characterization of Cu (II) soap complex solutions in benzene + methanol mixture has been studied and analysed by measuring density and surface tension parameters. This study confirms that CMC values depend upon solvent mixture composition and it is observed that CMC decrease with increase in chain length of copper surfactant (caprylate,caprate and laurate). It has also been affected by the polarity of the solvents as non- polar benzene and polar methanol were taken to analyze this effect. Szyszkowski’s empirical equation has been successfully applied to our referred system and it is found that the change in the behaviour of copper surfactant complex carried out at definite concentrations in different compositions of solvent mixture. It is also observed that the parachore of soaps solution increases with the mole fraction of the copper surfactant complex. The results show that there is justification in applying Hammic and Andrew’s equation to these complex solutions in benzene methanol mixtures.
